Got mine on Ebay:
[Link: ebay.com]I found a thread on another site with a pretty detailed explanation of changing this battery and mentioned soldering something from the old battery onto the new battery but the one in that post didn't have the pigtail on it already. was there any soldering involved with replacing your q50 battery or was it just pulling the remote apart and replacing?
